ARM: s3c24xx: drop s3c-camif setup platform code
The s3c-camif driver setup platform code does not have any users so it
can be safely removed.
Along with the code W=1 compile warnings go away:
arch/arm/mach-s3c24xx/setup-camif.c:28:5: warning: no previous prototype for 's3c_camif_gpio_get' [-Wmissing-prototypes]
arch/arm/mach-s3c24xx/setup-camif.c:56:6: warning: no previous prototype for 's3c_camif_gpio_put' [-Wmissing-prototypes]
